Is highway de-icing ‘a-salting’ our aquifers?

If you live in a cold climate, have you ever wondered where all the de-icing salt (or ‘grit’ as we call it in the UK) that gets spread on the roads in winter time ends up, aside from that accumulating salty grime that coats your car? As you might expect, most of the salt gets washed off the highways as the salt has the desired effect of melting the ice, or carried away by rain. This salty ‘runoff’ ends up in streams nearby via pipes which drain the highway.

Silurian tidal flat carbonates of the Tonoloway Formation

Journey to the Silurian period in what is today the Valley & Ridge province of eastern West Virginia to see some exquisite sedimentary rocks that represent deposition in a very arid, very shallow setting.

Monday Geology Picture: Salt Lamp

Although I haven’t yet featured such a gift on my annual What to Buy a Geologist for Christmas list, some of my wonderful relatives recently bought me a rock lamp for Christmas. Specifically, they bought me a pink colored Himalayan salt lamp. The lamp consists of a large crystal of salt, or sodium chloride, that is mounted on a pretty wooden stand. The lamp provides a lovely, soft, pale pink light. …

Monday Geology Picture: Pink Pan

Apologies for the recent gap in my blogging. I’ve been busy travelling for work, and our home internet connection was not working for a couple of weeks. We’ve also been suffering from regular power outages here in South Africa. Anyway, to make up for my recent quietness, I’m sharing a spectacular picture for this week’s “Monday Geology Picture” post. This picture was taken close to the border between South Africa …

Halite casts from Tonoloway Formation under the GIGAmacro lens

The work of team M.A.G.I.C. continues. This is a lovely sample quartet of salt cast samples from Silurian-aged Tonoloway Formation limestone. I collected these samples on Corridor H’s newly-opened section west of Moorefield, West Virginia, last spring. The big one at the bottom was collected by my friend Leigh Henry, who graciously loaned it to M.A.G.I.C. for imaging purposes.

Floe Lake hike

Last summer, my wife and I spent some time in the Canadian Rockies. One of the things we did was to take a three-day backpacking trip to Floe Lake, in Kootenay National Park, British Columbia. We picked a rough couple of days for hiking – We got a lot of Canadian Rockies precipitation out there: we got rained on, hailed on, and snowed on during those three days. Here’s our …

Monday Geology Picture: Salt Flat Reflections in Death Valley

Well, I still haven’t had time to write up a substantial blog post. I spent this past weekend writing my thesis, wrapping Christmas gifts (how can it possibly be Christmas next weekend?), writing Christmas cards (and wedding thank-you cards! Finally!), and spending some time with my husband, who arrived home unexpectedly yesterday. He’s been at sea on a sampling campaign, but there’s some trouble with the ship, so he’s home …
